Hi everyone.
We currently use tapes for our backup solution. I would like to move this to a nas box and then use the tapes to do a Weekly backup which I can put in the schools safe.
Our current daliy backup is getting close to 1TB so it would need to hold at least a weeks worth of data. Can someone please recommend me a good one. We use Backup Exec, dont know if that makes a difference.
Is there anything I should be aware of doing this?
Thanks
James
A 1TB backup!? Are you amending these tapes or is it a fresh complete backup every night?
Sorry, I rounded up. Our current backup is about 650GB but i'm allowing for growth.
Its a complete backup every night.
Do you run full backups each night? As Incremental would be alot better! We currently backup about 2.4TB each Friday to a custom built 28TB ubuntu server. Then each week night we backup the incremental stuff for the main file servers (full Sims Database copy though). If you want i can post the spec of the server which i bought (although if you want to run windows you would need to change the raid card as i run software raid.)
Overally it cost me circa 4K
ok thanks.
I didnt set up the backups, it was my predecessor. I like the idea of incremental backups. Would this work?
Monday - Full backup to NAS drive.
Tues -> Friday - Incremental backup to NAS.
End of month - Full backup to tape to store in safe.
Is it just user files you'll be backing up, not VM images or anything like that? If so, why not use rsync to copy the files from your main file server every night to your backup server, a different backup folder every day, but with the backup server running some kind of deduplication system (either a deduplicating file system or a script that does file deduplication). That way you could probably hold more than a week's worth of week's worth of backups, depending on just how many files are changed per day.Quote:

It uses it's own form of dedupe so 64 backups = 1 full backup + everything which has changed over the 63 days/backup slots. Therefore 2 tb will probably be able to hold your file server for however long you want it to, plus all of your other servers too.
Licences are less than £30 per server which is just slightly cheaper than backup exec.
(Personally I like dhicks suggestion but relying on a system which you aren't 100% on in this situation is a bit risky)
Could I ask to see the spec please?

we put 2 250gb drives in for the OS aswell in raid 1 (software raid) and then 16 x 2tb drives for the data which once formatted gives us 28/30tb i can't remember exactly.
Its a beast!
Best way to go!!!!!

It should simply be a case of paying for the right edition of Windows Server (and possibly CALs) and rsyncing files to a different backup folder each night, the server should take care of the rest. You'd just need a script to delete older backups when disk space hit a certain threshold value.Quote:

That way restoring user's files consists of simply pointing them at a read-only copy of their files on the backup server. File-level deduplication should work equally well, too.Quote:
